with common salt.” Mr. Parkes also gives an 
account of Mr. Hitt recommending, in a publica- 
tion more than fifty years ago, common salt. He 
says, after detailing the injury caused by the Honey 
Dew, “ if the season be wet, spread common salt 
all over the border, about eight ounces to each

thus ordered at all times when the Honey Dew 
appears on them, neither it nor the Smother Flies 
can ever do them much injury.” In speaking of old 
borders, which are weakened by vegetables grow- 
ing upon them, and if the weather is dry, he 
directs them to be watered plentifully three times 
a week, with one ounce of salt added to each 
gallon of water, and when the fly is strong, he 
recommends double the quantity of salt and water 
to be applied at the bottom of the trees. He says, 
“ I have found these methods successful, even when 
the flies have been very strong upon the trees, and
